What are aberrant right subclavian symptoms?
The most commonly reported symptoms related to compression of adjacent structures by aberrant right subclavian artery (arteria lusoria) were dysphagia (71.2%), dyspnea (18.7%), retrosternal pain (17.0%), cough (7.6%), and weight loss greater than 10 kg over a 6-month period (5.9%).
What is an aberrant artery?
Aberrant right subclavian artery (ARSA) is a rare anomaly, in which the right subclavian artery arises directly from the aortic arch instead of originating from the brachiocephalic artery. This anomaly should be taken into consideration during surgical procedures around esophagus, such as esophagectomy.
What is an aberrant left subclavian artery?
Left aberrant subclavian artery (LASA), also known as left lusoria artery, is a type of RAA branching, which takes-off distally to the right subclavian artery (as the last RAA branch) and usually crosses behind the esophagus to the left upper limb.
Does aberrant right subclavian artery require surgery?
Aberrant subclavian artery (arteria lusoria) is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention. The operative approach to correct this condition has been controversial.
How is aberrant subclavian artery treated?
A muscle-sparing right thoracotomy was used in the pediatric patients, and a supraclavicular approach was used in the adult. Patients were treated successfully by division of the aberrant right subclavian artery and translocation to the right common carotid artery, without graft interposition.
Does aberrant right subclavian artery need to be treated?
Aberrant right subclavian artery (RSA) is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention.
How many people have an aberrant right subclavian artery?
The right subclavian artery has an aberrant origin in 0.5% to 1% of the population. 1, 2, 3 Presence of associated symptoms is, however, even more uncommon. The most common symptoms include dysphagia, cough, and stridor, which are usually associated with evident compression of the appropriate structure.
Is aberrant right subclavian artery hereditary?
Although the diagnosis of an aberrant right subclavian artery is beginning to be used as a sonographic marker of aneuploidy and congenital heart defects, the etiology of this vascular abnormality could be related to genetic disorders.
Is ARSA a heart defect?
Similarly, ARSA was more common in the fetuses with trisomy 18 (P < 0.001) and all other chromosomal abnormalities (P = 0.002) compared with the normal fetuses. In the group of 2670 fetuses in which the RSA was successfully assessed, a cardiac defect was found in 120, 113 (94%) of which had a normal RSA.
